Look. It’s like this. Irritable Male Syndrome is called “having testosterone”. It is only caused by two things: (a) irritating women, and (b) other stuff that is irritating.

Guys looking for excuses for why they get pissed off at stupid stuff so they don’t have to blame themselves or whatever stupid shiznit they’re pissed off at are suffering from “lack-of-balls-itis”, not Irritably Masculine Syndromisity.
